Research shows that: with the increase of microwave power, drying rate Green Tea tea is also increasing. The vacuum degree is higher, the greater the drying rate. The less load, the greater the drying rate. The drying process is mainly divided into two stages of acceleration and deceleration, no obvious stage of constant rate of drying. Quantifying various factors on the drying rate, establishes the page mathematical model, provide a theoretical basis for the production of Green Tea.

China is a big country of tea production and consumption, Green Tea tea in China as one of the main crops, the annual output of nearly 150 thousand T, accounting for 1 / 4 of total tea consumption. Green Tea in fresh tea leaves as raw material, after fixing, rolling, drying and other tea making process produced. The drying process on the Green Tea after brewing tea, leaf color, Green Tea aroma quality factors is of decisive significance, is the most important link in the process of Green Tea.
